In this paper, a new method of line element fitting by means of Hough transformations is proposed in order to separate and recognize particle pathlines overlapping each other, on a digitalized flow visualization photograph. An image of particle pathlines is produced by a tracer method. Hough transformations are applied only to the edges of particle pathlines. The edges are obtained by tracing pixels that have high gradient value in the image. Results obtained by the method with Hough transformations are presented for the flow visualized images such that two particle pathlines are overlapping each other.
